Description

Technical Field

[0001] This utility model relates to the field of air purification, and in particular to a dual tungsten wire ion box for an electrostatic oil mist purification device. Background Technology

[0002] In the metalworking industry, CNC machining centers, such as CNC machines, require the use of various coolants during machining. During processing, these coolants can evaporate due to heat or splash into a mist, polluting the surrounding environment and affecting the health of workers.

[0003] Currently, mainstream air purification technologies are divided into filtration and electrostatic technologies. Filtration technology uses fibers and fiber-based filter materials to filter or adsorb pollutants in the air, thereby purifying the air. Filtration technology is characterized by its maturity and relatively stable operation; however, labor, material, operating, and maintenance costs are very high, and improper maintenance can pose certain safety risks. As filter materials continuously intercept pollutants in the air, the gaps between the fibers become increasingly clogged, increasing air resistance and requiring frequent cleaning and replacement of the filter materials. Simultaneously, bacteria and viruses trapped in the filter materials can lead to bacterial growth, mold growth, and unpleasant odors. Electrostatic technology uses an ionization zone to charge airborne particles. These charged particles are then adsorbed by the electric field formed in the dust collection zone, completing the purification process. Various high-voltage electrostatic dust removal devices designed using electrostatic technology principles can purify a wide range of particulate pollutants across a broad flow rate. They can achieve relatively stable operation under different temperature and humidity conditions and are well-suited for residential, commercial, industrial, and specialized applications. They feature long service life, high purification efficiency, low operating costs, and low maintenance costs.

[0004] The core component of the high-pressure oil mist purification device is the ion box, which includes an ionization section and a dust collection section. Airborne particles become charged in the ionization section, and these charged particles are then adsorbed by the electric field formed in the dust collection section, completing the purification process. There are significant gaps between the top and bottom of the dust collection section and the box body. This is primarily to protect the ionization and dust collection components of the ionization and dust collection sections during production, preventing damage during assembly. Due to airflow, after the particles are charged in the ionization section, they flow with the air to the dust collection section. Most of these particles are captured by the dust collection plates. However, because of the large gaps between the top and bottom of the dust collection section and the box body, particles entering these gaps cannot be effectively purified and escape with the air, thus affecting the purification efficiency of the ion box. Simultaneously, the grounding plate of the ionization section needs to avoid the high-voltage tungsten wire; therefore, clearance holes are provided at the top and bottom of the grounding plate. The voltage in the ionization section is relatively high, so the diameter of the clearance hole needs to be designed to be larger to ensure a safe distance. However, a larger diameter clearance hole will affect the ionization of the ionization section. The tungsten wire and the grounding plate form an ionization zone, but an effective charging zone cannot be formed between the tungsten wire and the clearance hole. Uncharged particles can easily escape after passing through the dust collection section, thus affecting the purification efficiency.

[0005] Chinese patent CN201620216288.0 discloses an ion box for an electrostatic purifier. The ion box includes a left end plate and a right end plate, with an ionization chamber and a dust collection chamber disposed between them. The dust collection chamber includes multiple alternating and parallel grounding plates and high-voltage plates. The grounding plates and high-voltage plates have a corrugated structure, and the corrugated structures on the grounding plates correspond and are parallel to those on the high-voltage plates. The ionization chamber in this patent includes multiple alternating and parallel sawtooth-shaped ionization plates and flat grounding plates. The sawtooth-shaped ionization plates have creases along their center line along their length. However, the sawtooth-shaped ion box is prone to sawtooth carbonization, resulting in a shorter service life. Utility Model Content

[0006] The purpose of this invention is to provide a dual-tungsten wire ion box for electrostatic oil mist purification equipment. This dual-tungsten wire ion box is applied in the air purification field of industrial electrostatic oil mist purification equipment and commercial kitchen fume purification equipment.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A dual-tungsten filament ion box for an electrostatic oil mist purification device includes a frame assembly, an ionization section, and a dust collection section, wherein the ionization section and the dust collection section are arranged side by side within the frame assembly.

[0009] The ionization section includes a plurality of metal plates and tungsten filament assemblies arranged alternately and in parallel with each other, and the ionization section is used to charge the passing air particles.

[0010] The dust collection section consists of several dust collection plates and is used to adsorb charged air particles.

[0011] In one embodiment of this utility model, the tungsten wire assembly includes a first tungsten wire, a second tungsten wire, and a fixing member, wherein the first tungsten wire and the second tungsten wire are disposed between the upper and lower fixing members.

[0012] In one embodiment of this utility model, the first tungsten wire and the second tungsten wire are connected to an external high-voltage power supply. The first tungsten wire and the second tungsten wire are used to release DC high-voltage electricity, typically 12-14kV.

[0013] In one embodiment of this utility model, a through hole is provided at each of the upper and lower ends of the metal plate.

[0014] In one embodiment of this utility model, the ionization section further includes two connecting rods. One connecting rod passes through multiple alternating upper end fixing parts and upper end through holes in sequence, and the other connecting rod passes through multiple alternating lower end fixing parts and lower end through holes in sequence.

[0015] In one embodiment of this utility model, several metal plates are fixedly connected to each other by a first screw.

[0016] In one embodiment of this utility model, several dust collection plates are fixedly connected to each other by a second screw.

[0017] In one embodiment of this utility model, the frame assembly includes a front end plate, a rear end plate, and a frame. The front end plate and the rear end plate are fixedly connected by several frame strips to form a frame structure. The ionization section and the dust collection section are arranged side by side within the frame structure.

[0019] In one embodiment of this utility model, the dust collection end plate is provided with a handle to facilitate equipment installation and operation.

[0020] The working principle of this invention is as follows:

[0021] Dirty air passes through a dual tungsten filament ionizer. The tungsten filament assembly releases DC high voltage (usually 12-14kV) through a high-voltage power supply. Air particles entering the ionization section are ionized and become positively charged. When the positively charged air particles enter the dust collection section, they are adsorbed by the grounded dust collection plate under the action of the electric field, thus purifying the air.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Compared with conventional ion boxes with a serrated ionization section, the dual tungsten filament ion box provided by this utility model has higher efficiency and less ozone release; there is no risk of serrated carbonization, resulting in a longer service life; and the tungsten filament is easier to replace than the serrated filament during later maintenance.

[0024] 2. The dual tungsten wire ion box provided by this utility model can be used in high humidity conditions. Thanks to the larger distance between the tungsten wire and the ground and the uniform discharge, the arcing phenomenon is effectively avoided, and it can be used in emulsion conditions.

[0025] 3. The dual tungsten filament ion box provided by this utility model can generate more ions simultaneously by adopting a dual tungsten filament design, thereby improving ionization efficiency and completing the task of cleaning and neutralizing air in a shorter time.

[0026] 4. The dual tungsten filament structure helps to generate a more uniform ion flow, making the ion distribution more consistent and ensuring a more balanced air cleaning effect throughout the working area; the dual tungsten filaments provide higher stability, maintaining good working condition even in continuous operation or high-temperature environments, reducing the failure rate; since the workload is distributed across two tungsten filaments, the wear of each filament is relatively reduced, thereby extending the overall service life.
